Rex Ryan and Kellen Winslow Jr. insist they’re not the least bit worried about the Jets tight end’s declining production since his impressive season opener. They say defenses have adjusted to take him away, which has opened things up for other players. But they say his time is coming.

“I’d blame it square on Marty [Mornhinweg]’s shoulders — put him under the bus,’’ Ryan joked Friday of his offensive coordinator. “But no, they certainly know where Kellen is, I’ll put it that way. [Defenses] know where Kellen is, and if I would’ve had my little TV thing up here, I could’ve showed you what I meant by it.

“But he allowed one-on-one’s [for receivers] on the outside. He has done a tremendous job for us. The guy works his tail off on the practice field. [He’s] a great teammate, but a very unselfish guy, and I think that’s really impressed me. I know it’s impressed his teammates as well.’’

Getting targeted eight times in the season opener, Winslow caught seven passes for 79 yards and a touchdown. Targeted six times in Week 2 at New England, he caught three passes for 16 yards, and quarterback Geno Smith didn’t throw his way once last Sunday. Asked if defenses have keyed on him since his big game against Tampa Bay, Winslow shrugged.

“I guess,’’ Winslow said. “Sometimes the ball just goes different ways. But it always evens out eventually. I would say they’re trying to jam me and stuff like that, but it’s man-to-man, it’s cover two or cover three. It’s not like I’m triple-teamed. They’re just trying to get their hands on me, and that gets other guys open.

“It evens out though, and we proved we can stretch the field, so guys can’t just sit low on us. They’re going to be scared to get run past. … It’s all about attempts and making plays. So when it comes my way, my job is to make a play. It’s coming, so I’m ready.’’

It might come his way Sunday. After coughing up a team-record 471 points last season, the Titans scrapped their old defensive system and now play man-to-man on nearly every down. After they allowed San Diego’s Antonio Gates five catches for 55 yards and a touchdown last weekend, Winslow could see chances in Tennessee.

“They play man-to-man the whole game and they rely on their front seven to get pressure,’’ said Winslow, who is 57 receiving yards shy of 5,000. “They’re coming after the quarterback and they’re going to live and die by man-to-man. It’s our job to be men and make plays for Geno, or whoever is in there.

“They’re attack mode on defense and man-to-man. As long as we protect, we’ll be fine. We just have to protect Geno and guys have to get open, we’ll be fine and make plays.’’
